FORD TAURUS FUSE PROBLEM

1994 Ford Taurus • 150,000 miles

My Taurus keeps blowing the 10 amp fuse in the engine compartment. This happened the first time a year then it did it again 1 month ago (11 months went by and no problem) and just yesterday it's doing it all the time and the engine won't kick over. I figured out it was the fuse for the ignition coil and when it blows the engine doesn't kick over. Any suggestion would be helpful as I am trying to figure out if I want to keep this car any longer or junk it.
